SABIC NORYL™ Resin PX0844 Polyphenylene Ether + PS (PPE+PS) (Asia)
Categories:	Polymer; Thermoplastic; Polystyrene (PS); Polystyrene + Polyphenylene Ether, Unreinforced
Material Notes:	NORYL™ PX0844 resin is a non-reinforced blend of polyphenylene ether (PPE) + high impact polystyrene (HIPS). This grade exhibits very low moisture absorption, hydrolytic stability, dimensional stabilty, good foam adhesion, and property retention over a wide temperature range. NORYL PX0844 resin is inherently UL94 HB and is an excellent candidate for automotive interior applications such as instrument panels, audio components, speaker housings, and interior trim. *see NORYL PX0888 resin for higher heat resistance. Features: Hydrolytic Stability,Low Creep Sensitivity Information provided by SABIC
